WATER-MOTOR.

Specification of Letters Patent.

Patented Apr. 18, 191%..

Application filed August 16, 1915. Serial No. 45,786.

To all whom it may concern:

Be it known that I, SAMUEL H. CARBIs, a citizen of the United States,residing at Freeport, in the county of Armstrong and State ofPennsylvania, have invented a new and useful VVater-Motor, of which thefollowing is a specification.

The present invention appertains to fluid motors, and relates moreparticularly to water motors, it being the object of the invention toprovide a novel and improved water motor for washing machines, althoughthe motor may be used for various purposes.

It is the object of this invention to provide a water motor consistingof but few parts, and which is simple and inexpensive in construction,without jeopardizing the utility and efliciency of the motor.

A specific object of the invention is the provision in a water motor ofnovel means for controlling the valves which control the inlet andoutlet of the water at the opposite ends of the cylinder.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed can be made within thescope of what is claimed without departing from the spirit of theinvention.

The invention is illustrated in the accompanying drawing, wherein Figure1 is a plan view of the motor as applied to a washing machine. Fig. 2 anenlarged longitudinal section of the motor taken on the line 22 ofFig. 1. Fig. 3 is a still further enlarged longitudinal section of themotor taken on the line 3-3 of Fig. 2. Fig. 4 is a reduced cross sectiontaken on the line 4l4: of Fig. 3.

In carrying out the invention, there is provided a cylinder 1 having oneend closed and the other end open, and a head 2 is secured to the openend of the cylinder. The cylinder and its head are each in the form of acasting, although they may be constructed'in various manners, and thehead 2 is provided with a central outstanding sleeve 3 through which thepiston rod or stem 4 1s slidable. That portion of the piston rod 41within the cylinder 1 is reduced in diameter, as at 5, and this providesa shoulder 6 movable within the sleeve 3 when the piston rod isreciprocated. The inner end of the piston rod is threaded into thepiston 7 which works within the cylinder 1, and the piston 7 is providedwith an integral collar 8 proecting centrally therefrom and embracingthe reduced portion 5. A rubber, fiber, or other suitable packing ring 9embraces the plston 7 and is held in place thereon by a wire orequivalent band. 10 embracing the packing ring.

The outer protruding end of the piston rod 4: is provided with a reducedthreaded extension 11 onto which one end of a rack 12 is adapted to bethreaded, whereby said rack can mesh with a pinion 13 secured to theupper end of the agitator staff 1 1 of the washing machine, as suggestedin Fig. 1. The motor may be attached to the washing machine in anysuitable or well known manner, whereby the reciprocation of the pistonrod 4: and rack 12 will serve to alternately rotate the stafi or shaft 11 in opposite directions.

The free end of the sleeve 3 has a stuiiing box 15 containing a packing16 embracing the piston rod 4, and a gland 17 is threaded into thestuffing box for compressing the packing, to prevent leakage.

Thehead 2 is provided with diametrically opposite intake and exhaustchambers 18 and 19, respectively, at the opposite sides of the sleeve 3,and the head is provided with integral nipples 20 and 21 forming inletand outlet ports for the respective chambers 18 and 19. The nipple 20can be connected by a hose 20 to a faucet or other source of water, andthe discharge water can be delivered from the nipple 21 through a hose21 applied thereto to a sink, drain, or the like. The head 2 is providedwith a pulsating chamber 22 of arcuate formation passing partiallyaround the sleeve 3 and having its ends disposed adjacent theChilIIbbers 18 and 19. The head 2 has restricted openings 23 and 24:between the. respective chambers 18 and 19and the ends of the chamber22, and has restricted openings 25 and 26 between the respectivechambers 18 and 19 and the interior of the cylinder 1. The openings 23and 25 are in alinement, as

well as the openings 24: and 26, and the axes of the two pairs ofopenings are parallel with the axis of the cylinder. A bushing 27 isthreaded into the opening 25 from the inner side of the head 2, andprovides a valve seat, and the outer side of the head is provided withan opening28 in alinement with the opening 24, a screw plug 29 beingthreaded within the opening 28 for normally closing the same.

A double puppet valve 30 is disposed within the intake chamber 18 andhas oppositely extending guide stems 31 and 32 working slidably withinthe opening 23 and bushing 27, respectively, to guide the valve 30 forreciprocatory movement. The valve 30 is seatable against the partitionbetween the chambers 18 and 22 for closing the opening 23, and isseatable against the bushing 27 for closing the passage through saidbushing leading to the interior of the cylinder. A puppet valve 34 isdisposed within the chamber 22 for controlling the opening 24, and has aguide stem 35 passing slidably through the openings 24 and 26 to guidethe valve 34 for proper reciprocatory movement. The stem 35 has areduced extension 36 projecting into the cylinder, and a second puppetvalve 37 is fitted upon the extension 36 and is secured thereon by meansof a pin or other securing element 38. The valves 34 and 37 thuscooperate to provide a double puppet valve for controlling the openings24 and 26 leading from the chamber 19 to the chamber 22 and interior ofthe cylinder, respectively. The valve 34 is seatable against thepartition between the cha1nbers 19 and 22, and the valve 37 is seatableagainst the partition between the chamber 19 and the interior of thecylinder. The inner end of the stem 32 has a reduced extension 33projecting into the cylinder 1 and corresponding with the extension 36.

The double puppet valves are operated by the movement of the piston rod4, and to this end, a yoke or plate 39 is mounted slidably upon thereduced portion 5 of the piston rod and its end portions slidablyembrace the extensions 33 and 36 of the double puppet valves. Cotterpins or other retaining elements 40 and 41 are engaged to the free endsof the extensions 33 and 36 respectively, for holding the yoke 39slidably upon said extensions, and to prevent the dis placement of theyoke upon the piston rod. A pair of spiral springs 42 and 43 aredisposed upon the opposite sides of the yoke 39 and have their largerends riveted or otherwise secured to the yoke, while the smaller ends ofthe springs which project in opposite directions slidably embrace the redueed portion 5 of the piston rod. The shoulder 6 of the piston rod 4 ismovable against the spring 43 when. the piston 7 is moved away from thehead 2, and the collar 8 of the piston or shoulder formed thereby ismovable against the spring 42. The yoke 39 has limited sliding movementupon the extensions 3.3 and 36 of the puppet valves.

The cylinder 1 is provided at one side with a longitudinal bypass orpassage 44 opening at one end, as at 45, into that end of the cylinderremote from the head, While the other end of the passage 44 communicateswith a passage 46 with which the head 2 is provided, said passage 46communicating with the intermediate portion of the pulsating chamber 22.

The operation of the motor is as follows :Supposing water under pressureis supplied through the nipple or intake port 20 to the chamber 18, withthe puppet valves arranged as illustrated in Fig. 3, the water wouldflow from the chamber 18 through the opening 23 into the chamber 22, andfrom thence through the passage 4644 into that end of the cylinderremote from the head 2, it being noted that the double puppet valve 30is seated against the bushing 27 to close the opening 25. The valve 34is seated to close the opening 24 while the valve 37 is unseated, toallow the water between the piston 7 and head 2 to pass through theopening 36 into the chamber 19 and thence out through the nipple oroutlet port 21, when the piston 7 is forced toward the head 2 due to thewater entering the cylinder behind the piston from the passage 4644.Now, when the piston moves toward the head, the collar 8 of the pistonstrikes the smaller end of the spring 42, whereby the yoke 39 is movedyieldably by the piston toward the head 2, and when the yoke 39 hasmoved slightly upon the extensions 33 and 36, it will move the doublepuppet valves outwardly, thereby seatin the valve 37 to close theopening 26, and unseating the valve 34. Now, the water from the chamber18 will pass through the bushing 27 into the cylinder at the head endthereof, to force the piston away from the head 2, and the water withinthe cylinder between the piston 7 and closed end of the cylinder will beforced out through the passage 46-44 into the chamber 22 and thencethrough the opening 24 and chamber 19 to the nipple or port 21. When thepiston 7 reaches that end of the cylinder remote from the head 2, theshoulder 6 of the piston rod 4 strikes the spring 43 and moves the yoke39 away from the head 2 until the yoke 39 strikes the pins 40 and 41 tothereby restore the double puppet valves to the position illustrated inFig. 3. The above operation is then repeated, it being noted that thereciprocation of the piston rod serves to operate the double puppetvalves properly to alternate the inlet and discharge of Water at theopposite ends of the cylinder whereby the motor will operate quickly andeffectively. The spring 43 when in the position illustrated in Fig. 2 isnot effective to resist the movement of the yoke 39 by the spring 42,the smaller end of the spring 43 entering the sleeve 3.

The motor is comparatively simple and inexpensive in construction,eificiently serves its purpose, and is not liable to get out of ordereasily. The other advantages and attributes of the motor will suggestthemselves to those skilled in the art Without further comment beingnecessary.

Having thus described the invention, what is claimed as new is:

A motor comprising a cylinder having a head provided "with anoutstanding sleeve, intake and exhaust chambers a pulsating chamber,openings between the intake and exhaust chambers and pulsating chamber,and openings establishing communication between the interior of thecylinder and the intake and exhaust chambers, the cylinder having apassage establishing communica tion between the pulsating chamber andthat end of the cylinder remote from the head, a piston working Withinthe cylinder and having a piston rod sliding through said sleeve, a pairof double puppet valves controlling said openings and having stemstt'epiee of thin patent may be obtained for five cents each, byafldretaflng the Commissioner of Patents,

projecting into the cylinder, the portion of the piston rod Within thecylinder being reduced in diameter and providing a shoulder, the pistonhaving a collar embracing the piston rod, a yoke slidable upon thereduced portion of the piston rod and slidably engaging said stems, andspiral springs having their larger ends secured to the yoke at theopposite sides thereof and having their smaller ends slidably embracingthe reducedportion of the piston, said shoulder and collar beingarranged to move against the respective springs when the piston reachesthe opposite ends of the cylinder whereby the puppet valves areoperated.

In testimony that I claim the foregoing as my own, I have hereto aflixedmy signature in the presence of two witnesses.
